VOLTAGE REGULATOR WITH INDEPENDENT PEAK AND AVERAGE VOLTAGE SENSING

摘要

A voltage regulator for a generating system having a main generator and an exciter for providing field current to the main generator includes a device could to the main generator for sensing at least two operating parameters thereof. Components are coupled to the sensing means for generating pulse width modulated (PWM) signals based upon the first and second sensed operating parameters. Components are coupled to the first and second PWM signals for comparing the pulse widths thereof. The PWM signal having the narrower pulse width is coupled to a switch for controlling the current delivered to the exciter. The exciter current is therefore controlled in accordance with one of the sensed parameters at any particular time.
